public virtual void LoadGame(
	int Slot,
	bool InMemory
)

If there is no data in the specified slot, an error occurs. Use SaveExists(Int32, Boolean) to determine if data is available to load from a particular slot. Counters that were not included in the SaveUnit will retain the same value they had before the game was loaded. Similarly, maps that are not included in the save unit will retain the same state they had before the game was loaded instead of being reset or loaded from the file. One exception is if AllMaps was ever included in the SaveUnit (even if some maps were later excluded). In this case, all maps that were not included in the SaveUnit will be reset next time they are visited.
